Dive back into science news with the Interronauts! Jesse and Sophie are back with a brand new episode, studio, the whole kit and caboodle (kitten cavoodle?). They talk about why it is that the fittest Tassie devils are most likely to succumb to the deadly facial tumours, how to pipe renewable hydrogen, why some shark mammas hook up with multiple pappas, and they speak with Dr Lisa-ann Gershwin about her to-date co-discovery of 204 species of sea animals (including a DOLPHIN!).

Multiple partners is the way to go for some sharks

A grey reef shark swimming

We used DNA analysis in our multiple paternity study and found grey reef shark litters have more than one father.

“In a recent study of sharks caught by fisheries in Papua New Guinea (PNG), a team of researchers looked at a breeding strategy called multiple paternity, which occurs when a litter of baby sharks has more than one father. Such litters are made up of both full and half siblings,” from our blog. Learn more about the study here.

Researcher looks at hydrogen tech

“It’s colourless, odourless, the most abundant element in the universe, and may one day take you from 0-100 on the highway. It seems as though hydrogen is a pretty logical choice for clean fuel of the future. The kicker is that there’s very little pure hydrogen to be found anywhere on Earth, meaning we need to somehow produce it,” here’s more from our blog.
